If Europeans are irked by the Wii U's odd time-based shopping rules for mature content, they'll at least have Windows 8 as their refuge. As of today, Microsoft is accepting Windows Store submissions for PEGI 18-rated games: the move will let Grand Theft Auto IV, The Witcher and future adult-focused titles come to Windows' official shop in countries where PEGI holds sway. European players undoubtedly reap short-term rewards by getting quick access to the releases they'd previously had to locate in other channels. We're more interested in the long run, however -- when developers no longer have to guess at whether or not games will pass Microsoft's certification gauntlet in Europe, they're more likely to welcome Windows 8 with open arms instead of running in the opposite direction.
